Preventing Winter Dieback on Red Carpet Roses: Stop Late Fertilizing and Spring Pruning

Brown leaves falling in winter result from late fall fertilizing, which promotes tender growth killed by cold. Red Carpet roses are hardy in your zone if allowed to go dormant.

Fix

No fertilizer after September.
Spring: cut back to 8 inches to remove dead wood and stimulate healthy canes.
